摘要

In recent years, especially in geotechnical engineering studies, the relationship between the engineering properties of the soil can be determined through the increasingly frequent use of statistical analysis methods. Standard penetration test results, shear wave velocity (Vs) and electrical resistivity measurements were evaluated during the investigations on different soil types in Şırnak city centre and surrounding settlements. To obtain these correlation equations, correlation and regression analyses were applied to the collected data, investigating linear and nonlinear relationships, and the most suitable relationships and their corresponding correlation coefficients were determined. SPT tests have been conducted in every borehole opened in the field, and N values have been determined. In contrast, the wave speeds were measured at the same points as these drillings. These include SPT-N, shear wave velocity and SPT-N electrical resistivity correlations. The correlations were analysed using three methods: Pearson correlation, simple linear regression and Spearman’s coefficient test analysis. As a result, the regression and correlation relationships obtained are fundamentally based on the geotechnical properties of the examined fields and the amount of data processed.
